Hi All, I can confirm that there is no 64K tracks limit on DSORG=DA data sets. I inherited a number of Adabas databases and they use DSORG=DA. One of my larger databases has a data storage component that is 240,525 tracks (16,035 cylinders) in 9 extents across 8 volumes.
Organization . . . : DA Record format . . . : F Record length . . . : 5064 Block size . . . . : 5064 1st extent cylinders: 363 Secondary cylinders : 1668 Allocated cylinders : 16,035 Allocated extents . : 9 The rules are documented here: https://www.ibm.com/support/knowledgecenter/SSLTBW_2.3.0/com.ibm.zos.v2r3.idad400/mdss.htm Cheers, Mick.
